16 Enterprise Architecture Strategies Learned The Hard Way

via Cio Dashboard:
  1. An exhaustive enterprise level blueprint is virtually impossible to build – it’s too big and no one will buy-in
  2. The best strategy blends a direction-setting enterprise blueprint and business unit and domain blueprints
  3. Centralized accountability for the EA function is a predictor of success
  4. A centralized team of architects is critical in driving EA standards and approaches
  5. Architects must be assigned to projects as core team members (60%+ of total EA FTEs) rather than “advisors”
  6. EA should be measured in 2 ways: business capabilities delivered and costs of core services
  7. Measure EA as an asset – what does it cost to provide the service and what return does the business get from the business capabilities delivered?
  8. Architecture leadership requires strong management, business operations and technology skills, most likely in 3 different types of people; don’t expect your chief architect to run the EA function
  9. Methods and governance must be integrated into existing work processes (eg, project approvals, SDLC) rather than a new overlay
  10. Enterprise Architecture is not always the best name for communicating; maybe Strategy & Planning or Enterprise Transformation is better
  11. The best large companies have “business architecture” teams reporting to the business (or dual reporting to business and IT)
  12. Leading companies have reference architectures in place for 90% of the technical domains
  13. Your senior enterprise architects must have the right cultural skills and awareness to integrate well with upstream business partners and downstream technical users
  14. High performance groups maintain consistent, formalized EA involvement in the SDLC to translate blueprints into sufficiently detailed starting architectures for each project as well as accurate cost and resource estimates
  15. Mature organizations target 40% EA resource time for strategic planning and 60% on SDLC tasks, and typically err on spending more time on SDLC tasks
  16. Strong credibility and trust amongst Business and IT partners is a predictor of EA success. Credibility has typically been gained via joint strategic planning efforts, one project at a time.
